[spoiler][/spoiler]Guys, I put everything you need to know in my post.

I put the density of lead and tin in their grains per cubic centimeter, I provided the volume of the bullet in cubic centimeters and did the math for you.

I don’t think any of you read my post that showed that the bullet in question is a 50-50 mix of lead and tin by volume.

There is the small possibility, that because of the shape of the lead atom that the tin atom might be able to hide within the matrix to some degree, resulting in a decrease in volume with a mixture of the alloy, But I don’t think so.
